and exact description, reference being had to the accompanying drawings, forming a part ,of this specification.

My invention relates to conveying mechanism of the type disclosed in my- United States 4Patent No. 7 97,100, issued August 15, 1905, my invention being an improvement upon the general class of conveyers shown in The conveyer of my presin connection with ocomotives and is employed for transferring fuel from locomotive tenders to the locomotive lire boxes.

While the apparatus lof my invention is of principal utility in connection with locomotives, and while the invention ismost generally realized in connection with locomotives and their tenders, Idonot wish to be limited altogether to this embodiment and adaptation of my invention.

In the device of m aforesaid patentLI em loy a c onveyer tu e containing universal yjointed sections of aconveying screw and adapted to hold fuel being conveyed from the fuel box to thelocomotive fire box, but have found the construction as set forth in said patent, is not best adapted to locomotive practice, and I, therefore, in the preferred embodiment, form the {conveyer `tube or trough in `universally jointed sections, one section being stationarily 'mounted upon the tender, while thecoinpanionsection extends from the tender to the lire box of the locomotive. By reason ofthe universal joint between tlie sections of the conveyer trough or tube, the locomotive and tender' may 'oscil-v late or rockin passing over rough or curved tracks, without im airing the said trough. i I have further foun in practice that' the device of my aforesaid patent is not bestada t ed to locomotive practice, "for` the flirt er reason that the locomotive and tender ,have violent movement longitudinally with respect to each other`owing\ to the considerable lost motion in the'cou lers uniting theflocomotive and tender. overcome this "difficulty by permitting the ltroughr to"'"m`ove` longitudinally with respect-to one of its supports, preferably that sup ort which ositions the trou h in front o the boiler oor, to which end port of sufficient length and with a hole of sufficient size, so that, notwithstanding the degrees ofrelative movement between the locomotive and tender, the hole in said troufgh support is always in position to have the uel discharged from the trou h through the-hole into the fire box of the boi er. ploy an injector where the fuel finds passage into the fire box, which injector is operated by a suitable rime mover, and, in accordance with anot er feature of my invention, I drive the conveying screw that is located in the conveyer trough, by means of flexible sh'afting that is interposed between this prime mover and the tail .of the conveying screw. In this way, power is a plied to the conveying screw at its rear end which is preferred practice) without the necessity of employing an additional prime mover, and, in order that the rate of operation of the conveying screw may be regulated without modifying the speed of the prime mover, I employ desirably construct this sup- 3' reference to the accom anying drawing,

showin the preferred em odiment thereof,

Figure 1 is a view in side elevation, partially' 1n section, of conveying mechanism constructed in accordance with the preferred embodiment of the invention, said conveying mechanism being disposed u on the decks l'of the locomotive and itsten er. Fi 2 is fa lan view of certain of the parts s own in ig. 1, some of the parts being broken away and removed in order that certain of the characteristics' of the structure may be more clearly revealed. Fig. 3 is a sectional view on line 3 3 of Fig. 4. Fig. 4 is a sectional view on line 4 4 of Fig. 3. Fig. 5 is a sectional view on line 5 5 of Fig. 2.

Fig. 8` is a cross-sectional view on line8 8 of Fig. 2,. Fig. 9 is a detail showin the manner of connecting sections of tIi shafting'inter osedbetween the prime mover andthe tail o the conveying screw. 'I

e flexible Like parts are indicated by smnlar acters of reference throughout the different figures. l

- The conveyer trough 10 is desirably of the shape indicated, this trough being formed in two sections, the rear and horizontal section bein desirably stationarily mounted upon the cgleck 11 of the locomotive tender, this section of the trou h extending into the fuel bunker of the ten er. The forward section of the conveying trough is carried at its upper end in a saddle 12, as will more fully appear, and at its lower and in a saddle 13 that` I 2 5 pivot 17, the directions of the saddle and the contiguous portion of the yoke are maintained paral el and the pivotal bolt 1 7 is prevented rom receiving undue stress. It will be seen that the inclined section of the conveyer trough is adapted to turn about the pivotal bolt 17, furmshing one axis of rotation, and is also adapted to turn about the stud shafts 18, 'arranged in the ends of the yoke 14 transversely to the bolt 17, and furnishingv an axis of rotation for the tilted member of the conveying trough that is angular to the axis of rotation furnished by the olt 17. In this way, a universal joint of one form is constituted, that is, the joint thus 40 formed affordsmotion sufficiently universal for the slanting section of the trough to full the purpose of my invention. The lower end of the slanting section of the conveying trough being supported as it is upon the tender, the upper section is desirabl 'supported upon the saddle 12, that'is pivota ly mounted at 19 upon the housing 20 ofthe fuel injector. Thepivotal mounting 19 permits the upper end of the slanted section of the conveylng trough to oscillate as relative lateral movements between the locomotive and tender occur, while, in order to compensate for relative longitudinal movements of the locomotive and tender, due to lost motion in the coupler that unites said locomotive and tender, the slanting section of the conveying trough is permitted to slide in said saddle l2, this being the preferred mechanism for permitting a sliding relation between the conveyer trough and its mounting to com ensate for the lost motion at the coupler. passage for fuel is aiiorded through the housing 20, which passage desirably communicates with an openmg 1n the door of the iire box of a locomotive boller, and through which passage fuel may be thrust into the said lire box, by means of the in'ector blades 21 that are rotated by a suitable prime' mover 22. An openin is provided in the saddle 12, throu h whic i fuel is received from the trough, an an opening 23 70 is provided in said trough, which is longer than the corresponding onenin in the saddle 12, so that the `passa e into the housing 20 need not be restricte owing to the reciprocation of the slanting section of the conveyer trough. The conveying screw 24 is divided into sections, one for each section of the conveyer trough, which screw sections are universally jointed or hinged at 25.

By the construction thus far specifically described, it will be seen that no matter what may be the relative movements between the locomotive and tender, the conveyer trough always adapts itself to said movements, and the universal joint between the sections of the conveying screw being in line with the axis of rotation furnished by the shafts 18, there is no material relative longitudinal movement between the slanting section of the conveyer trough and the section of the conveying screw located therein, the said sections of trough and conveying screw maintainin roper relative positions, irrespectiie relative movements between the locomotive and tender. It is desirable to operate the conveyin screw by applying driving force to the ta thereof, to which end I interpose shafting formed of universally jointed sections 26, between the prime mover 22 and gearing 27 housed at the tail of the screw and there connected with the screw. It is desirable to employ a constant speed prime mover for operating the injector blades 21, and, in order that the rate at which the fuel is fed may be regulated, I include in the flexible shaftin inter osed between the prime mover an the tag of the shaft, a suitable form of changeable speed gear 28 including a suitable speed change lever 29. As the speed change gear illustrated is of a well known ty e, I do not deem 'a detailed description t er'eof to be essential.

In order that longitudinal movement between the locomotive and its tender and the motions of the locomotive in roundin curves may be com ensated for in the exib e shafting, the two orward sections 26 of'said shafting are preferably formed in sub-sections united as indicated in Fig. 9. Referrin to Fig. 1, the upper section 26 is `thus forme in 120 su -sections to compensate for relative longitudinal movements between the locomotive and tender, while the next and lower section 26 is thus formed in sub-sections to compensate for the movements of the locomotivein rounding curves.

I have not deemed it necessary to illustrate the locomotive and its tender com letely, having deemed it suflicient to show tllie deck 11 of the tender and the deck 30 of the loco- 130 motive and the rear boiler head 31 of the locomotive, through which boiler head fuel is to be injected by way of the housing 20.

I use the term trough herein in the sense of any suitable conveyingv passage. I use the term tender hereln in the sense of afuel vehicle that is separately formed from the locomotive, for if the locomotive itself carriedits fuel, there would be no need for some of the Jfeatures of my present invention. In the claims, therefor, the term tender is used in the sense of a separate vehicle that is coupled to the locomotive.

It is obvious that changes may readily-be made 1n the preferred embodiment of my invention shown and specifically describedf without departing from. the spirit ofv my invention, and I do notbtherefore, wish to be limited to the precise construction illustrated, but,

Having thus described my invention, I claim'as new and desirel to secure by Letters- Patent 1.`The combination with two vehicles in theform of a locomotive and tender, of a conveyer for transferring fuelr from the tender to the locomotive fire box, said conveyer having a support uplon one vehicle and a second support u on t e'other vehicle, with respect to which atter support it is slidable.
